HOT-#WATER Boites..

SPECIFICATION forming part of Letters Patent No. 388,893, datedSeptember 4, 1888.

Application tiled July 14, 1888 Serial No. 279,995.

To if/ZZ zul-7,0711, t may concern.-

Be it known that 1, EUGENE SOLOMON MANNY, a citizen of the Dominion ofCanada, and residing in the city and district of` Montreal and Provinceof Quebec, Canada, have invented certain new and useful Improvements inHot-Water Boilers; and I do hereby de clare that the following is afull, clear, and exact description 4of the same, such as will enableothers skilled in the art to which it appert-ains to make and usc thesame.

My invention has reference to a hotwater boiler in which thereturn-water, instead of going into the boiler at its lower portion,enters by the top and descends within the boiler, thus avoiding adisadvantage met with in all the hot-water boilers receiving thereturnwater at the bottoni-that is, the cooling of the coal next to thepartition where the cold water enters, and thus this coal does not burn,or burns very i'mperfectly, as it is keptin a black state most of thetime.

The object of my invention is to provide a hot-water boiler having theadvantages of not cooling the coal in the fire-box, and of beingcompact, cheap, and quick of action.

Referring to the drawings, similar letters refer to similar partsthroughout the several VIEWS.

Figure l is a front elevation shown halt' in section, and the upperportion shows a section through aa of Fig. 2. Fig. 2 is a sectionthrough .fr x' mi mi, and Fig. 3 is a plan view taken at y y.

As there is nothing new about the tirebox, grating, or ash-pan it isuseless to describe them. However, around the tire-box A is placed awater-leg, B, the object of which wiil be expiaincd hereinafter. On topof this waA ter-leg, which is rectangular, Fig. 3, is placed apartlycylindrical portion, C. In this latter is placed the twopartitions D and E, these serving to support the water-lines F, in whichare placed horizontal partitions G. Consequently, the flames and hotgases ascending from the re-box A strike directly on the partition E andwater-dues F and O, thus heating them to a very high temperature, thesmoke and gases escaping through the opening H. On the front I of thecylindrical portion C is placed a castiron front end, J, provided withthe doors K and tire-box door L. Now, the action of iny hot-water boileris very simple. The return-water flows in at M M, as shown by arrows,and thence through the (No model.)

rectangular passage N, where, continuing to go downward, acertainportion passes through the water-dues O, which are larger than those forthe hot water and designated by F; but they are kept in position at oneend by the partition D, and at the other they are inserted into thepartition of the passage N. This rcturn-water, however,gets heated asitdescends, and when it enters the water-leg B at I? it is comparativelyhot, so that it does not cool the burning coal placed next to thepartition of the water-leg opposite the entrance I?. The water then runsaround thc irc-box A in the waterleg B, as shown by arrows, and thenascends through the aperture Q, into the space R, where it ascends, acertain portion of the heated water going through the partitioned ducsF, so that by the time it passes out into the distribution-pipes T T, asindicated by arrows, it has reached a very high temperature. Thewater-leg B is smaller inseciion opposite the fire-box door L-that is,there is a depression in the casting, as shown at V in Figs. 2 and 3.Moreover, the water-leg B is partitioned off between the inlet I? andthe outlet Q. the object of which is to stop the direct passage ofacertain portion of the returnwater into the outlet Q.

As can be seen, the main advantages of my hot-water boiler are thenot-cooling action of the return-water on the hot coal in the fireboXopposite its inlet; also, it possesses a very quick action and is cheapof manufacture.

The partition D can be left out, if desired. In that case the door Kserves to give access to the waterflucs and clean the space betweenthem.

Having described my invention, what I claim, and desire to secure byLetters Patent,

In a hot-water boiler ofthe class described, the combination,\vith thetop returning-pipes, M M, passage N, and Waterfiucs C' and F, with thewatcrleg B, the openings P and Q, the partitions D E, and fire-box A,substantially as described, and for the purposes set forth.

In testimony whereof I have affixed my signature in presence ofthe twosubscribed witnesses.
